I'm not a big fan of teleconverters, but the 50mm lens is the best lens to use one with. The 50mm f1.7 would be a better choice still though.

Thanks John.
Wondered if you could explain your reason for not being "a big fan"?

The more layers of glass you introduce the lower the image quality.
I tried a 2X adaptor on a 300mm lens, the resulting images were VERY poor. That's an extreme example but it's the same for all lenses to some extent.

I'm not a big fan because the quality is invariably very poor.

I have this one, and its the best 2x tc I've tried. All tc's will reduce some IQ, but this one is not too bad. I also got a quantaray 2x tc (which I suppose is the same as the sigma, usual with quantaray) and in terms of sharpness I see no discernible difference except the tokina gives more purple fringing (nothing to bad).
